-virtio: bounce.in_use==true in virtqueue_map_desc()
-Description of problem:
-
-Steps to reproduce:
-1. Build EDK II (edk2-stable202311) for riscv64
-2. Build UEFI SCT (commit 81dfa8d53d4290) for riscv64
-3. Run the UEFI SCT
-4. Observe the message "qemu: virtio: bogus descriptor or out of resources" after which the execution stalls.
-
-The full procedure is described in https://github.com/xypron/sct_release_test
-
-To save time you can call `sct -u` and select only test 'MediaAccessTest\\BlockIOProtocolTest'. Run it with `F9`.
-Additional information:
-virtqueue_map_desc() may be called for a large buffers size `sz`. It will then call dma_memory_map() multiple times in a loop. In address_space_map() `bounce.in_use` is set to `true` on the first call. Each subsequent call is bound to fail.
-
-To verify this is the cause I applied the following diff:
